Ingredients

Instructions

  1. Step 1: Preheat oven to 350°F (175°C). Cream 1/2 cup softened butter and 3/4 cup granulated sugar in a bowl with an electric mixer until light and fluffy, about 3 minutes.
  2. Step 2: Beat in 2 large eggs one at a time, then add 1 tsp vanilla extract and mix until combined.
  3. Step 3: In a separate bowl, sift together 1 cup all-purpose flour and 1 tsp baking powder. Gradually add the flour mixture and 1/4 cup whole milk alternately to the butter mixture, mixing gently until smooth.
  4. Step 4: Pour the batter into a greased 8-inch square baking pan and bake for 25-30 minutes until a toothpick inserted into the center comes out clean. Cool completely.
  5. Step 5: Once cooled, cut the cake horizontally into two layers. Spread 1/2 cup raspberry jam evenly over the bottom layer and press the top layer back on to form a sandwich. Cut into 16 equal squares.
  6. Step 6: To make the chocolate coating, sift 2 tbsp unsweetened cocoa powder and 1 1/2 cups powdered sugar into a heat-proof bowl. Add 1/2 cup boiling water and 2 tbsp melted unsalted butter and stir until smooth and glossy.
  7. Step 7: Dip each cake square into the chocolate mixture, then roll in 1 1/2 cups desiccated coconut to coat. Place on a wire rack to set before serving.
